I replaced stock Dunlops with KTC 80 tires front and rear. Huge improvement on 2011 KLR 650. Completely different bike off road with these tires. Good on road. Hard to tell you are running on knobby tires when on pavement. I have 1500 miles on and off road. No noticeable wear of front tire rear tread is worn down about 1/4 of the total knob depth. So 3/4 tread left. Looks like I will get 3000 to 4000 miles on rear and at least twice that on front. I only got 1200 mile on rear Dunlop. Tread life is not great but the improvement in off road performance is worth it. Great 50/50 tire I like them and recommend them for anyone who rides on and off road.

I've used the TKC-80 TwinDuro tires on my 2006 Triumph Scrambler for two years with 80% use mainly off road adventure riding in Colorado and Utah. These have held up great and the traction is excellent for their design. I've carried camping equipment food gas and supplies on these trips camping out several nights in the boonies and even with the extra weight added they have handled very well. Only tire I'll run due to confidence both on and off road.

I replaced a 140 Heidenau with a 130 TKC on my hopped up KLR. The 140 I replaced was really to big it rubbed and I had to cut the chain guard and it was tough to bead so I went with the 130 I see this tire on a lot of KLR's and it is definitely a lower profile I noticed a slight weaving at freeway speeds and will have to drop my forks a few mm to stop it thats not really a problem it works great on the street and handles stutter bumps and rides better than the Heidenau but the traction SUCKS. My worn out Heidenau would hookup on the hard stuff and this TKC will spin . I might have been a little high on air I was running 30 hot off pavement most hard pack and small rocks but this tire just did not want to hook up. I cant rate the durability yet but I have seen enough of them to know it will not last as long as the front which is how long the heidenau lasted gra

The "B" in a tire size indicates that the construction of the tire is Bias Belted. The Q is the speed rating of the tire. Bias Belted tires are able to withstand a heavy load like a really heavy enduro bike or 2 up riding, but the speed rating is lower than that of a radial tire.

Thanks guys but the point was to get Chaparral to list the complete information. TKC 80's are now made in the same size in both TT (tube type) and TL (tubeless). The TKC's are now made in both TL and TT for this size. So you cannot buy the correct tire unless they add TT and TL to the website description.

I used this on a DR650 that I sealed the spoke nipples on without tubes and it worked great. There was a slight leak on the bead at first but after the first ride it sealed itself. Put over 1K miles on it before selling the bike.
